Year of construction: 2015, condition: new, We have a MATICA Espresso card printer available. This printer is bought by us in 2015 and has been standing in the showroom. Price new ist € 1.599,-, price now is € 999,- We have come to the conlcusion that this type of machinery is not the type of machinery we are able to offer as a distributor in a correct manner. Therefore this printer is new and has just printed max 10 cards in its life. Single or double side edge-to-edge Optional Magstripe and Smart Card encoder Ethernet and optional WiFi Prints up to 850 cards per hour 100-card feeder The Matica Espresso II is a compact and powerful desktop ID card printer, that is a brainchild of Italian design & engineering and reflects German reliability in consistent performance. The Espresso II offers great value and versatility with extraordinary printing speed and outstanding print quality. With its robust and durable construction, the Espresso II looks and works great in any office or card production environment. The Espresso II is a single side desktop ID card printer for projects needing printing only on one side. The Espresso can be field-upgraded to easily double the printing capacity with the duplex printing feature. Any Espresso II printer can evolve to duplex anytime, anywhere without the need to install additional hardware components. Contact and contactless smart card encoding are also field-upgradable features. Fgodpjfnldqefx Apwsb LED status indicators on the front of the printer allows you to monitor the card production process at a distance, and the blue LED light on the card hopper door keeps you aware of your card input availability in real time. You can also use optional single card manual insertion for individual card printing as needed. Each printer comes with a rear output hopper to catch full card runs as needed, which can improve the throughput speed in higher volume scenarios. In standard setup, having front-side input and output trays is also convenient for situations where space is limited, in a desktop environment, a cabinet or under a counter. Each Espresso II printer also has the option for inline magnetic stripe, contact chip or contactless smart card encoders, to maximize its functionality for a broader set of application uses, such as access control, time & attendance, payment services, and many more. The entire line offers Ethernet connectivity and optional WiFi making printing and encoding convenient and trouble-free. You can easily define your printer and choose the one that perfectly matches your current needs, as Espresso II offers a vast range of options. Whether or not your requirements evolve in the future, you have still the possibility of making an upgrade by adding functionalities to your existing configuration. The new printer line works perfectly for a wide variety of applications such as Employee and Membership ID Badges, Service and Benefits Cards, Gift and Loyalty Cards, Access Control Cards, Student IDs, and Transit Cards, just to name a few. The Espresso II is available with different specifications ​— modules, encoding, color, etc..
